Arotinolol Hydrochloride: A β-Adrenoceptor Antagonist

Arotinolol hydrochloride (S-596), β-adrenoceptor antagonist, shows high affinities for both β1- and β2-adrenoceptors. Reportedly, It shows a moderate affinity also for α-adrenoceptor, and the mean ratio of α:β = 1:8. In addition, its main metabolite (the 2-thiophenecarboxylic acid, AC-623) also shows affinity for β-adrenoceptors. Arotinolol is widely used in the treatment of high blood pressure. (The product is for research purpose only.)
